From the makers of Star Realms (Who made the original Ascension Deckbuilder game, and were also a bunch of M:tG heavyweights)

The premise is that the game comes with 4 balanced decks to play right out of the box, but then it has the cards and rules set up to play sealed or draft games built in. With extra sets, you can create "Epic cubes"

It's basically a knock off of Magic, with draft and sealed styles built in, and no collecting needed. So, bascially how they took their Ascension creation, and made a cheap small box version with more gameplay modes with Star Realms....they did this same thing for what is basically Magic.
